Abstract

The invention relates to the field of ferrite sheet preparation, in particular to a preparation process for a thin ferrite sheet. The preparation process comprises the following steps that (1) a ferrite raw material is pressed, a thick ferrite sheet is obtained, and the thickness of the thick ferrite sheet is 10-20 mm; and (2) the thick ferrite sheet obtained in the step (1) is subjected to sintering, slicing and washing. According to the preparation process for the thin ferrite sheet, the using amount of the raw material is decreased, the yield of the thin ferrite sheet and the efficiency are high, deformation is not prone to occurring, and the rejection rate is low.

Description

technical field [0001] The invention relates to the field of preparation of ferrite sheets, in particular to a preparation process of thin ferrite sheets. Background technique [0002] Ferrite is a metal oxide with ferromagnetic properties. In terms of electrical properties, the resistivity of ferrite is much larger than that of metal and alloy magnetic materials, and it also has higher dielectric properties. The magnetic properties of ferrite are also shown to have higher magnetic permeability at high frequencies. Therefore, ferrite has become a widely used non-metallic magnetic material in the field of high frequency and weak current. [0003] The existing thin ferrite sheet preparation process generally uses ferrite raw materials such as Fe 2 o 3 , ZnO and Mn 3 o 4 Direct pressing into thin sheets requires a large amount of raw materials, low efficiency, easy deformation, and high scrap rate. Contents of the invention [0004] In view of the shortcomings of the p...
